Flashing Overdrive OFF light...

[CAT]

Hello Guys,
I have problem with my LS400 Automatic gearbox...
when overdrive is switched on while driving it starts flashing overdrive off light... Also on few first miles it seems like it is shifting from 1st to 3rd gear (missing 2nd). after some time everything come back (2nd gear) and no flashing light..
Please advice something...


Regards,
CAT

Bridge TE1 and E1 in the Diagnostics box on top of the motor.

The O/D light will flash a code (or multiple)

Then check the code against.

I had the same thing in my older Celsior, for me it meant that my tranny was in "limphome mode". I replaced a TPS as that was giving errors, then it ended up taking a month in the shop before they replaced the solenoids which fixed the problem. I hope yours is an easier fix.
